Why aren’t spacecrafts constantly missing their marks when planets like Mars are basically infinitesimally small, moving targets that are speeding through outer space?
Because the orbits of planets are observed for a long period of time, their future position is really well predictable. With a lot of math, a high precision at launch of the spacecraft and well planed mid-flight corrections via swing by at other planets, the spacecraft could meet with planet, whe…
The Short Answer
Because the orbits of planets are observed for a long period of time, their future position is really well predictable. With a lot of math, a high precision at launch of the spacecraft and well planed mid-flight corrections via swing by at other planets, the spacecraft could meet with planet, where it was predicted. So even landing on a comet like Rosetta was possible.
